I’m back home from the AT&T store to give you eight minutes with the 875U. I can’t overstate how large this AirCard is; should be fine for most notebooks, but UMPC owners will want to take this into consideration. I’ll be testing the actual power drain on the Q1P when using this card since it does have an internal battery. I’ve tried to use the card without the battery but it won’t work. Honestly, I’m on the fence with this device for my personal use. It might be just the ticket for some folks, but I’ll be carefully weighing the pros and cons over the next 30 days. I was very impressed by the download speeds when in an HSDPA coverage area; better than what I’ve had with EV-DO. But is that enough to overcome the bulk and potentially large battery drain?
